According to research commissioned by Vision Direct, the average American adult will spend the equivalent of 44 years of their life staring at screens. Yikes.

While we can’t just quit our jobs and throw away our computers and phones, there are steps we can take to keep our peepers healthier. Here are five easy tips for folks who stare at screens all day, as suggested by optometrist Dr. Selina McGee.
